HeatTech Floor Heating Products Applications

Where can HeatTech electric radiant floor heating system be installed?
Bathrooms, showers, kitchens and mud rooms are just a few examples of common floor heating applications. HeatTech mats and cable are also suitable for heating engineered wood and laminate floors in other parts of the house. HeatTech is great both for residential homes and apartment building heating (especially where hydronic warm floor heating systems are not allowed) and fits well both in new construction and remodeling projects.

Which types of finished floors are compatible with HeatTech cable and mats?
Ceramic tile, stone and granite are best heat conductors with excellent heat transfer properties and high thermal mass, and therefore are perfectly suited for use with HeatTech radiant heating products. Hardwood, engineered wood, laminate and vinyl are also suitable floor coverings. The total R-value of the floor coverings should not exceed 1.0 (this information can be obtained from flooring manufacturer). For further assistance, contact our Technical Support.

Which types of subfloors are compatible with HeatTech cable and mats?
Plywood and backer board (cement board) are most common subfloor types used for electric radiant floor heating installation. Concrete slabs with smooth surface and mortar beds are also acceptable.

Are HeatTech radiant floor heating products suitable for bathroom/kitchen retrofits?
At only ~1/8” thick, HeatTech cable and mats will not raise the floors significantly and do not require any structural or architectural considerations, making them well suited for kitchen and bath remodeling projects.

Safety and Durability of Electric Radiant Floor Heating Systems

Are HeatTech products safe?
Both HeatTech electric radiant floor heating cable and mats are UL listed for USA to ensure safe performance in a wide range of installations. HeatTech products do not create electromagnetic field (EMF) that interferes with home appliances, phones and personal use devices.

Can HeatTech products be installed in wet areas, such as bathrooms showers, etc.?
HeatTech warm floor cable and mats are perfectly suited for installation in such areas. Note, however, that as with any other electric radiant floor heating system, HeatTech must be installed on a dedicated class “A” GFCI (GFI) breaker with a thermostat which has a built-in GFCI, such as Honeywell/Aube model TH115-AF-GA. A waterproof membrane with negligible R value must also be included in the installation to protect the cable from moisture.

How long will HeatTech radiant floor heating system last?
When properly installed and used, HeatTech floor heating system should last a lifetime.

Product Sizing and Selection

For product selection and sizing-related questions, please refer to Sizing page.

Electrical

What size area can I heat using HeatTech mats/cable?
Whether for 120V or 240V systems, the total combined thermostat load must not exceed 15 Amps.

For 120V systems, this translates into:

  • 150 sq. ft maximum coverage for mats and/or cable (cable installed @ 3” spacing).
  • Up to 200 sq. ft for cable installed @ 4” spacing.

For 240V systems:

  • 300 sq. ft maximum coverage for mats and/or cable (cable installed @ 3” spacing)
  • Up to 400 sq. ft for cable installed @ 4” spacing.

If the floor exceeds 300 sqft, we can provide special controls which allow to control up to 3,000 sqft of heated space using only a single master thermostat.

What kind of heat output can I expect from HeatTech system?
At 3” heating cable spacing, HeatTech electric floor heating system will output about 12 Watts per square foot (which translates to 40-41 BTU) and thus allows to use the system as a single source of heat. All mats have cable pre-spaced at 3” apart, whereas spacing for cable-only floor heating installations can be varied within acceptable range (see Installation manual for details) and is also best kept at 3” spacing. Read more about system heat output here.

Can I combine cable and mats?
As long as both are of the same voltage, total system load does not exceed 15 Amps and there's not more then (3) of cable/mats combined, they can be connected to the same thermostat. For side to side mats and cable comparison, visit Mats vs. Cable page.

Will I need a GFCI?
A GFCI (Ground Fault Circuit Interrupter) is required for electric heated floors and especially for areas where moisture may be present. Examples include bathrooms, showers, kitchens and mud rooms. A class “A” GFCI must be installed on the line powering the electric floor heating system and additionally, a thermostat with built-in GFCI may be required (such as Honeywell/Aube TH115-AF-GA).

Which power output is optimal?
HeatTech cable and mats are designed to output 12 Watts per square foot, equal to 41 BTUs, therefore meeting and exceeding typical residential heat requirements of 25-35 BTUs per sq. ft. More about 12W and 15W heating systems.
